A chemical reaction occurs inside a cylinder with a movable piston at constant pressure of 0.972 atm. The chemical reaction releases 431.6 J of heat to the surroundings. Before the reaction occurs the volume of the cylinder is 3.38 L. During the reaction the cylinder is forced down to a final volume of 0.94 L. Calculate the change in internal energy for this process (in joules). _________ J
Please answer and no reject ,need max in 30 minutes thank y It is reported that a gas is taken through a series of five operations, finally arriving at the same temperature, pressure, and volume it possessed originally Step 1: the system absorbs 220 kj of heat and performs 300 k) of work on the surroundings Step 2: the system loses 110 kj of heat while he volume constant Step 3: 110 kj of work is done on the system and it absorbs 60 kj of heat Step 4: the system loses 160 kg of heat while the volume remains constant Step Sithe system absorbs 290kj of heat and does 220 kj of work on the surroundings Can you say whether this report is corrected or not?

QUESTION 4 Calculate the work done (in Joules) during the gas-phase hydration of ethylene to produce ethanol in which the volume of the gases changes from 33.81 L to 16.90 L at a constant pressure of 5.223 atm and temperature. C 2H 4(g) + H 2O(g) ↔ C 2H 5OH(g) The product of pressure and volume change should give units of L*atm. It can be shown that 1 L*atm = 101 J. Key Concept:: Work is accomplished by causing a volume change at some pressure: w = −PΔV where ΔV = the change in volume
